Supply-demand balance (MWh)#
indexed by asset, data type (Demand or Production), energy, node, technology and test case
Description#
This KPI returns the volumes of energy consumed and produced over the entire simulation for every energy, node, asset, and technology of a given context (except for CO2 energies: see specific KPI).
The results indicated in this KPI are directly those of the optimization problem. If an asset produces, it will appear in the Production tag of the “Data type” index.
For example, a storage asset may appear in both the Production and Demand tags, as it consumes energy to store it and produces energy during its life cycle.
Modelling hint
Note that Voluntary Load Curtailment, which represents consumption curtailment, and Loss of Load, which represents failure, are modelled as production assets. They will therefore appear in the Production tag.
This KPI is particularly interesting to understand the equilibrium between the national production and the national demand over a node for a given energy.
Calculation#
The equations below are valid for any realization and are therefore implicitly indexed by test case. Index Technology is directly deduced from the asset.
Production#
Let be \(x_{a, e, n}\) the value returned by the data type Production for a given asset \(a\), energy \(e\) and node \(n\). We can then express \(x_{a, e, n}\) as:
Consumption#
Let be \(x_{a, e, n}\) the value returned by the data type Consumption for a given asset \(a\), energy \(e\) and node \(n\). We can then express \(x_{a, e, n}\) as:
